Purpose :
Evaluating anti-scarring therapies requires objective assessment of scarring, and knowledge of normal fornix anatomy. Measurement of conjunctival scarring has focused on inferior fornix shortening, whilst reduction in superior fornix depth (FD) is often overlooked. There is data on normal FD in South Asians, but no studies investigating normal conjunctival FD in Caucasians.

We designed a custom- made fornix depth measurer (FDM) for objective measurement of upper and lower conjunctival FD. The purpose of this study was to evaluate intra- and inter-observer variability, and to establish a reference for normal conjunctival FD measurements in a Caucasian population.

Conclusions :
Using an alternative custom-designed FDM, central conjunctival fornix depth in Caucasian eyes appears to be similar to data previously reported in South Asian eyes. Fornix depth measurements were repeatable and reproducible.
